The Munich Artist Sigi Bußinger (www.sigibussinger.de) had a dream: His work – a three meter large blue star – should start shining solely powered by renewable energy. At the Munich Headquarter of AquaSoli now this “green dream” comes true every evening: In the river of the Auer Mühlbach a 5 kW Microturbine plus an “on-shore” photovoltaik installation jointly deliver the necessary voltage for the art projekt. The PV installation was planned and errected by AquaSoli whose engineers are worldwide working for renewable energy projects (www.aquasoli.de). Both forms of energy – water as well as solar – are getting integrated by a special energy management system which charges the connected accumulators and supplies the “star art” of Sigi Bußinger with the necessary energy.
